Harris Corporation to Receive Technical Emmy(R) Award for ATSC Broadcast Transmission System RF Filters

PR Newswire (US)
CINCINNATI, Oct. 23 /PRNewswire-FirstCall/ -- Harris Corporation
(NYSE:HRS), an international communications and information
technology company, will be awarded a Technology & Engineering
Emmy(R) Award from the National Academy of Television Arts and
Sciences (NATAS) for developing special transmission filters that
help broadcasters improve the quality and reduce the costs of
operating digital television signals. Harris will be presented the
award for developing the ATSC Broadcast Transmission System RF
Filters at a ceremony January 7, 2008, at the International
Consumer Electronics Show (CES) in Las Vegas. The ATSC RF filter
technology, which was awarded a U.S. patent in 2005, was pioneered
by Robert J. Plonka, principal engineer with Harris Corporation
(now retired), to overcome potential quality and interference
problems stemming from operating adjacent analog and digital
channel assignments. The resulting band-pass RF filters maintain
highly reduced side-band emission levels to eliminate interference
with other signals in adjacent channels, particularly when
broadcasting at full power DTV with dual-purpose capability to use
that same filter as an adjacent channel combiner. In November of
2000, KFSN-TV, the ABC affiliate in Fresno, Calif., became the
first station to employ the technology in its broadcast operation,
broadcasting its digital signal on VHF channel 9. Today, the ATSC
Broadcast Transmission System RF Filters have become an
industry-standard component deployed across a variety of ATSC DTV
transmission platforms by third-party vendors Tim Thorsteinson,
president of Harris Broadcast Communications, said, "We're thrilled
to have been selected by NATAS for our efforts to advance ATSC
signal transmission through the use of sharply tuned band-pass RF
filters. Today, DTV stations in the United States use these RF
filters to stay in strict compliance with FCC specifications.
Ensuring that DTV signals maintain highly reduced side-band
emission levels means that adjacent spectrum may be used reliably
for other purposes without the risk of interference." Additional
